I'm inheriting a mess and I need your help to straighten it out.
The two primary objectives are to alter the DNS records for 'Example.com' so that the "internally hosted" email server (Domain registrar and email server host are the same) continue to function, while the domain itself points to an "externally hosted" web site.
Here's the information:
1. 'Example.com' DNS is managed at Company A.
2. 'Example.com' A Record points to OLD site hosted by Company Z.
3. 'Example.com' NEW site exists as a user (~exampledotcom) on an account with Company B.
4. 'Example.com' Email server runs on virtual host account with Company A.
Currently, the DNS entries for 'Example.com' that exist on Company A are as follows (Type, Name, Data)
A Record, example.com, [IP address of Virtual Server hosted by Company A that powers Email server but does NOT host current OLD site] A Record, www.example.com, [IP address of OLD site] MX Record, example.com, Pref=10 example.com Then all standard CNAME entires point to 'example.com'
If I'm understanding the current setup correctly, "they" are pointing 'example.com' to the email server address JUST so they can set the MX Record as 'example.com'. Couldn't you simply change the MX Record to the IP Address of the email server?
How do I need to arrange my name servers? Does the NEW site hosted with Company B need to be on a dedicated IP so that I can set Example.com's A Record to that?
